SHOE-SPILE HASP.

sPEoI IoATIoN forming part of Letters Patent No. 781,006, dated January 31, 1905.

' Application filed August 25, 1903. Serial No. 170,698.

T 0 all whom it may concern/.-

Be it known that I, J osEr'KNoPs, a citizen of the German Empire, residing at AiX-la- Chapelle, Germany, have invented an Improved Shoe-Spile Rasp, of which the following is a specification. Y

My present invention relates to an improved shoe-spile rasp, and has for its object to provide an adjustable spile-rasp the handle of which can be displaced in respect of the special rasping-plate, so that instead of two rasps of different shapes used hitherto the improved rasp can be used for all purposes. One of the rasps used hitherto has an oblique shaftand is designed for rasping the spiles in the sole, especially in the foremost part of the latter, while the other rasp, having a straight vertical shaft and provided with a circular rasping-plate, isdesigned for rasping the spiles above the heel.

The rasping-plate of the improved spilerasp can, if worn out, easily be replaced.

The shoe-spile rasp is illustrated in the accompanying drawings, in which- Figu re 1 is a side elevation of the shoe-spile rasp. Fig. 2 is the front view of the same. Fig. 3 is a perspective view of the same. Fig. 4 is the top view of the rasp; and, finally, Fig. 5 is the top View of the special rasping- .plate separately.-

Similar characters refer to similar parts throughout the several views.

The under end 2 of the shaft 1 of the spilerasp is flattened, and its undermost part is bifurcated to form two eyes 3. The flattened shaft 2 is provided with a slit 4:. By means of a screw-bolt5 the shaft is pivotally fas tened to the eyes 6 of the quadrangular frame 7 loosely arranged-upon the rasping-plate 8. In the middle of this'plate there is integrally connected to the said plate an eye 9. ,The above-named screw-bolt 5 penetrates the eyes 6 of the frame 7 as well as the eyes 3 of the shaft 1 and the eye 9 ofthe plate 8, thus conthe plate 8.

Through the slit 4 of the flattened end 2 of the shaft 1 is guided a bow 10, made of a strip of thin sheet metal and provided all along with a longitudinal slot 11. The how 10 is secured by rivets 12 to the side faces of the frame 7, and its ends are fastened, by. means of small screws 13, to the body of therasping-plate 8; Through the-same slit 4 of the shaft 1 penetrates an arc-shaped plate 1 1,- arranged over the bow 10 and provided with a I by means of the adjusting-plate 14 and the screws 15, in an oblique position, as shown in Fig. 3; but for rasping the spiles above theheel I secure the shaft 1 to the plate 8 in a straight direction, as represented in Fig. 1. I prefer to make the heads of the screws 15 quadrangular in shape, which,.leaning against the flat side surfaces of the shaft 1, prevent the screw-bolts from rotatingand being loosened.

The quadrangular frame 7, leaning against the upper surface of the rasping-plate 8, is

destined to transfer the power executed on the shaft 1 unto the ra'sping-plate and makes the whole instrument a solid one that offers vsuflicient resistance to the pressureof the workman. When the rasping-plate 8 is worn out, I loosen the screws 13, as well as the bolt 5,-and can hereafter replace. the plate by another;

Having now particularly described and ascertained the nature of my invention and in what manner the same is to be performed, I declare that What I claim is:-

An adjustable shoe-spile rasp having in combination a rasping-plate, a shaft pivotally secured to said rasping-plate and provided, with a slit, a frame pivotally connected with said shaft and loosely arranged upon said rasping-plate, a slotted bow passing through the slit of said shaft and having its ends remov ably attached to said rasping-plate and permanen tly secured to said frame, an adjustable bow-shaped plate passing through the slit of said shaft in juxtaposition to said slotted boW, and means for securing said shaft at any suitable angle to said rasping-plate, substantially as set forth. 10

In Witness whereof I have hereunto set my hand in presence of two witnesses.
